Comparative Measurements of Low-Frequency Attenuation in the Deep Ocean Employing Sinusoidal and Explosive Sources.
Abstract
The paper describes a deep-water propagation experiment involving the use of both explosive sources and towed sine wave projectors in the Sofar channel of the North Atlantic. It was conducted with the objective of narrowing the list of potential causes put forth to explain the well-documented but unexpectedly large attenuation coefficients which have been reported by determining whether the observed anomalies stem from fundamental differences in the sources employed or from mechanisms associated with the medium. The study initially considers the conformity of coefficients in the 354 to 3540Hz region for the impulsive measurements in this instance with previously reported values. (Modified author abstract)
